JOHN M. GAAR, OF RICHMOND, INDIANA, ASSIGNOR TO GAAR, SCOTT & COMPANY, OF SAME PLACE.

STRAW-STACKER.

SPECIFICATION forming part of Letters Patent No. 325,526, dated September 1, 1885.

Application filed Juno 1S, 1885.

To all whom it may concern:

Be it known that I, J onn M. GAAR, a citizen of the United States, residing at Richmond, in the county of \Vayne and State of Indiana, have invented new and useful Improvements in Straw-Smokers, of which the following is a specification.

This invention relates to that class of straw stacker-s which receive the straw from the thrashing-machine, and in which the strawcarrier or conveyertrough is capable of swinging horizontally about a fixed center or pivot and thereby distributes the straw over a semicircular area.

The object of my invention is to simplify and make more convenient and durable the various parts of a straw-stacking machine, whereby the straw-carrier can be raised and lowered with facility and turned to any desired position or angle with relation to the main frame of the machine without interrupting the progress of the work.

My inventionconsists in certain peculiarities in the construction and combination of devices for raising and lowering the strawstaeker, for turning it to any desired position and holding it steady at any required angle with the main frame, and for folding it compactly for transportation, all of which will be hereinafter more fully set forth.

In the annexed drawings, illustrating my invention, Figure 1 is a perspective view of my improved straw-stacking machine, showing the conveyor-trough extended and turned at an angle with the main frame. Fig. 2 is a side elevation of the stacker mounted on goalso the lower end of the king-bolt 6, that (No model.)

forms a pivot for the extended conveyer trough in turning laterally to any desired angle with the main frame.

Above the main frame 1,and secured to its sills 2 2 and to one of the crosspieces 3, is a ring, 7, preferably formed of T-iron, as shown. This circle serves as a brace or stay and also as a brake for the stacker or conveyor to hold it at any desired angle with the main frame and prevent it from being blown from side to side, as will be presently described.

Mounted loosely on the king-bolt 6, above the circle 7, is a yoke, 8, theupper end of which is attached to and supports a bolster, 9, that is centrally pivoted on the upper end of the king-bolt. The bolster 9 carries at its ends the arms 10 10,that support the pivoted 10 10 are provided with flanged guidelugs 12 12, for supporting the segment-racks 13 13 in operative relation with their actuating-pinions 1a 14, the latter being rigidly secured to the opposite ends of a shaft, 15, which is provided centrally with suitable bearings,l6 16,that are secured to the bolster 9, as shown in Fig. 1.

The shaft 15 is provided with a spur-gear, 17, that is actuated bya worm-shaft, 18, having a crank-handle, 19, by turning which the conveyer-trough 11 can be raised or lowered at will to any desired position.

The conveyer-trongh 11 may be made in the usual form with folding sections for convenience in transportation, and is provided with the ordinary canvas side guards, 2O 20, and with a traveling apron, 21, that is passed over rollers 22 at the ends of the trough, one of said rollers having a shaft, 23, which carries a sprocket-wheel, 24, that is connected by a chain, 25, to a shaft, 26, which is journaled in bearings 27,atta-ched to the under side of the bolster 9. The shaft 26 extends only about half the length of the bolster 9, and is provided at its inner end with a bevel-pinion, 28, which meshes with a loose bevel-gear, 29, on the king-bolt 6, which loose gear 29 in turn meshes with a bevel-pinion, 30, on the inner end of a shaft, 31, that is mounted in bearings 32 on the circle 7, or other fixed support.

To the outer end of the shaft 31 is fixed a sprocket-wheel, 33, that is connected by a end of the conveyor-trough 11. These arms chain, 34, to a similar sprocket-wheel, 35, on the driving-shaft 5, which is provided with a driving-pulley, 36, that receives power by suitable belting from a pulley on the thrash ing-machine, or from any other convenient source.

By power applied to the driving-pulley 36 the conveyerapron 21 will be actuated continuously, through the intermediate mechanism, so as to carry the straw through the conveyer-trough 11, the latter being'meanwhile capable of turning or swinging horizontally to any desired angle with the main frame for the purpose of distributing the straw over the stack as required.

It is obvious that the conveyer-trough 11 can be readily turned from side to side, to-

gether with the bolster 9 and supporting-arms 10 10, by reason of the flexible connection of the shafts 26 and 31 through the bevel-gears 28 29 30, one of said shafts, as 31, being mounted in fixed bearings, so as to maintain its conncction with the driving-shaft, whilethe shaft 26 is journaled in bearings attached to the bolster 9, so as to be capable of turning therewith.

The supporting-arms 10 10 are connected by adjustable chains 37 to a friction clamp or shoe, 38, that is capable of sliding on the flanged surface of the circle 7 as the bolster 9 and superimposed parts are swung horizontally during the operation of stacking, the circle 7 and shoe 38 thus serving as a brake to steady the conveyor and its supports while the machine is in use.

A movable dog or brace, 39, is pivoted to the main frame 1, and has its upper end so formed as to be capable of fitting against one side of a beveled shoulder, 40, on the upper part of the tilting frame 4, a stationary brace, 41, being arranged on the opposite side from the movable dog 39, and acting in conjunction therewith to steady the stacker when elevated.

The conveyer-trough 11 or stacker proper is raised and lowered by the segmental racks 13 13 and pinions 14 14, as before explained. These racks and pinions also hold the conveyer-trough at any desired elevation without the use of any catch or fastening. It will be seen that the upper ends of the segmental.

racks 13 13are firmly secured to the sides of the convcyer-trough, and are so arranged that their toothed upper surfaces will always be held to mesh with the pinions 14 14 by means of the flanged guide-lugs 12 12, on which thelower ends of the racks are supported when the con veyer-trough is elevated. When the stacker is lowered and folded for transportation, as shownin Fig. 2, the racks 13 13 rest on lugs 42 42, secured to the sides of the main frame. B

15, with its gear 17 and pinions 14 14, will be actuated so as to move the. segmental racks 13 13, and thereby elevate the stacker to any desired height.

accomplished by simply reversing the move- The lowering of the stacker is.

ment of the crank. WVhen the stacker is elevated and extended, it can be readily turned horizontally to any desired angle with the main frame without disturbing the operative mechanism of the straw-carrier or conveyerapron. This results from the flexible connection or gearing of the shafts 26 and 31, as before explained. In whatever direction the stacker may be turned it will be securely braced and held from accidental movement by the friction-clamp 38 and its connections, as well as by the dog 39 and brace 41, hereinbefore described.

After the conveyer-trongh has been lowered and folded the pivotal gear-frame 4 may be tilted by throwing back the dog 39 and use of the crank so as to throw the king-bolt 6, bolster 9, and arms 10 10 backward, thereby affording a support forthe forward or pivoted end of the conveyer-trough, reducing the height of the load, the rear end of which is now supported by a cross-bar, 43, attached to the standards 44 at the rear end of the truck, ,as shown in Fig. 2. In this condition the stacker is ready for transportation.
